Overview
Vitu’s Nutrition feature uses Google Gemini AI to analyze photos of your food and provide detailed nutritional breakdowns. Simply snap a picture of your meal, and the app instantly identifies what you’re eating and estimates calories, proteins, carbohydrates, and fats.How to Use
Take a Photo
Tap the “Tomar Foto” button on the Nutrition screen. You’ll see two options:
- Cámara: Take a new photo with your device camera
- Galería: Choose an existing photo from your gallery
Wait for Analysis
The app sends your photo to Gemini AI for analysis. You’ll see a loading indicator with the message “Analizando imagen con IA…”This typically takes 5-20 seconds depending on your internet connection.
What Data is Tracked
For each meal photo you analyze, Vitu captures:- Dish Identification: Approximate name of the food detected
- Calories: Total energy content in kilocalories (kcal)
- Macronutrients:
- Proteins (shown in green on the chart)
- Carbohydrates (shown in amber on the chart)
- Fats (shown in red on the chart)
The AI analysis is personalized based on your profile data (age, weight, height, gender) to provide more accurate nutritional recommendations.
How Results Are Displayed
Nutritional Breakdown Cards
After analysis, you’ll see four color-coded chips showing:- Calorías: Total energy with a fire icon
- Proteínas: Protein grams with a green leaf icon

Troubleshooting
”No se seleccionó imagen”
This means no photo was chosen. Try again and select a photo from the camera or gallery.”Gemini no devolvió respuesta”
The AI service didn’t respond. Check your internet and try again.”No se pudo estimar nutrientes”
The AI couldn’t identify food in the image. Ensure your photo clearly shows a recognizable dish.API Key Issues
